Introduced to the public at the 1998 North American International Auto Show, the Oldsmobile Alero was an instant hit with the automotive press and consumers alike. For 2002, both a sedan and a coupe are available, with your choice of four trim levels and two engines. While the Alero is technically a replacement for the Achieva, this stylish compact is light years ahead of previous attempts by the division to build and market a small car. GX and GL1 models now feature an all-aluminum 2.2-liter DOHC four-cylinder that generates 140 horsepower. With twin balance shafts to smooth out vibrations and offering much improved fuel economy, this engine is a welcome improvement over the previous powerplant. A four-speed automatic is standard on all models with a five-speed manual optional on models equipped with the new four-cylinder.
